Given Grove Karl Gilbert’s legacy of high-caliber fieldwork, coupled to process-based studies, there can be few more deserving recipients of the G. K. Gilbert Award than Prof. Michael Church of the University of British Columbia. Primarily a field scientist, his extensive investigations on Baffin Island, his backbreaking work establishing necessary sampling criteria for gravel bar sedimentary studies, and other works on gravel bed river dynamics have been complemented by flume experimentation and computational studies on process dynamics.
In addition to statistical rigor, three other great attributes of Mike’s research are mechanical insight, as exemplified by work with Rob Ferguson on grain settling velocity; an ability to critique and interrogate foundational concepts, as shown in his groundbreaking work with Olav Slaymaker on how equilibrium scaling for specific sediment yield breaks down when a postglacial sediment pulse is working its way through a landscape; and a keen reflective and philosophical strand to his thinking, with particular focus on the nature of scale, associated phenomena such as allometry, and the history of the discipline.
Mike has also been a pivotal figure in the education of professional and academic geomorphologists in Canada and farther afield. His undergraduate hydrology course, with the requirement to deploy calculus, graphical techniques, and conceptual reflection in order to succeed, left a deep impression on me on how such classes should be devised. At graduate level, that Mike’s numerous students themselves have gone on to make significant contributions to the field is testament to the way in which Mike helped hone their critical and technical faculties while they worked with him.
I am sure that a great many colleagues from around the world will join me in expressing their delight that AGU has seen fit to award the 2017 G. K. Gilbert Award to Mike.
